Window Balance Assembly

A window balance assembly comprising:

• a carrier extending along a first longitudinal axis and comprising a housing having an interior space, an upper end and a lower end;
• a mounting bracket disposed at the upper end of the carrier;
• a spring comprising a first portion at least partially disposed in the interior space of the carrier and a second portion extending outside of the interior space of the carrier and engaging the mounting bracket;
• a receiver supported in the carrier near a lower end of the carrier and comprising a cam rotatable about a second axis between a first position and a second position wherein rotation of the cam between the first and second positions operates to increase a dimension of at least a portion of the window balance assembly;
• wherein, in an uninstalled configuration of the window balance assembly, a single tab at a lower end of the mounting bracket releasably engages the upper end of the carrier to connect the mounting bracket to the carrier and opposes a force of the spring against the mounting bracket to prevent the mounting bracket from rotating relative to the carrier about a third axis that is generally parallel to the second axis;
• and
• wherein while the tab is preventing rotation of the mounting bracket about the second axis, the tab does not prohibit relative twisting and sliding movement between the carrier and the mounting bracket to disconnect the mounting bracket and the carrier from one another and allow movement between the carrier and the mounting bracket generally in a direction along the first longitudinal axis.
